STAPLE-SETTING HVI PLEiVl EMT.

SPECIFICATION forming part of Letters Patent No. 579,538, dated March23, 1897.

Application filed February 2'7, 1896. Serial No. 580,955. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH P. I'IASTY, a citizen of the United States,residing at Superior, in the county of Nuckolls and State of Nebraska,have invented a new and useful Staple-Setting Implement, of which thefollowing is a specification.

My invention relates to an improved staplesetting implement; and it hasfor its object the production of a device for setting wire staples inmending articles of leather or other like fabric, the implement beingadapted to force the ends of the staple through the fabric, turn thepoints inward, and clench them, thus securing the pieces of fabrictogether.

The invention will first be described in connection with theaccompanying drawings, and then pointed out in the claim.

Figure 1 of the drawings is a View in elevation of my improvedimplement, the stapleholder, plunger, and a portion of each jaw beingsectioned. Fig. 2 is a perspective view of the plunger. Fig. 3 is a planview of the head-plate and the staple-holder. Fig. 4 is a brokenperspective view of the staple-holder, showing a staple therein. Fig. 5illustrates a modified form of myinvention, showing a plan view of thestaple-holder and the head-plate and a perspective View of the plungerused in such modified construction.

Referring to the drawings, A A represent two levers, the rear ends ofwhich form handles and the front ends being curved to form jaws B B.These levers are pivotally connected at 1 and normally held in openposition by a coil-spring 2 in rear of the pivotal point, as shown inFig. 1.

0 represents the staple-holder, preferably rectangular in shape andhaving a central hole 3. In the holder in communication with the hole 3and extending laterally therefrom are formed a number of recesses 4:, 5,6, and 7, each of which extends on each side of the hole 3 and nearly tothe bottom of the holder. These recesses are adapted to receive thestaples, as shown in Fig. 4;, the first two, 4 and 5, being preferablyformed at a right angle to each other, the remaining two, 6 and 7, beingat an acute angle to the first two and to each other.

D represents a plunger which comprises a stem 8, the lower end of whichis reduced at 9, and'a cap 10, secured to the upper end of the stem.From the cap project laterally arms 11, 12, 13, and 14, each extendingbeyond the edge of the cap on each side and being adapted to work in therecesses 4, 5, 6, and 7, respectively, the arms being of a height lessthan the depth of said recesses, as shown in Fig. 1. The plunger D isadapted to work in the holder 0, its arms lying in the respectiverecesses therein and its stem projecting throughthe central hole 3. Theshouldered end 9 of the plunger is passed through a hole 15 in the lowerjaw B and secured thereto by a nut 16. The jawB, surrounding the hole15, is recessed, as at 18, forminga seat for one end of a coil-spring19, which encircles the stem 8 of the plunger and bears at its upper endagainst the bottom of the staple-holder, as shown in Fig. 1, by whichconstruction the cap and arms of the plunger are normally held to thebottom of the holder.

E represents a head-plate having a stem 20, which is passed through anopening 21 in the upper jaw B and secured in place by a nut 22. In thesurface of this plate are formed a series of concave depressions 23, solocated that when the staples are in place in the holder a depressionwill be directly above each end of each staple.

The staples F are placed in the holder, one lying in and being heldupright by each respective recess.

In Fig. 5, I have shown a modified form of my invention, in which thestaple-holder O is formed with parallel recesses 24:, 25, and- 26. Theplunger 1) has lateral arms 27, 2S, and 29, adapted to fit and work insaid re cesses, and the head-plate E has concave depressions 30,arranged and in sufficient number to coact with the staples placed inthe recesses. The securing of the modified construction to the jaws andits operation by the handles will be understood without furtherdescription.

The parts being assembled as above described, the staples having beenplaced in their respective recesses, the operation of my improvedimplement is as follows: The ends of the fabric to be mended are broughttogether, preferably overlapped, and placed be* tween the head-plate andthe holder above the ends of the staples. By pressing 011 the handlesthe parts on the jaws are moved together until the holder contacts Withthe under side of the material and the head-plate with the upper side.Further pressure on the handles Will cause the plunger to move graduallyupward against the stress of spring 19, causing the staples to be forcedout of the holder and into the fabric. When the ends of the staples havepassed through the fabric, they will enter the depressions in theheadplate, following which they will be caused, on continued pressure onthe handles, to form return-bends 011 themselves and reenter the fabric.l/Vhen the plunger has moved upward until its upper surface lies flushwith the upper edge of the holder, the staples will have been forcedentirely out of the holder and into the fabric, the head-plate havingcaused the ends of the staples to have been clenched therein, thusforming a secure junction of the pieces of the fabric.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a staple-setting implement, the combination, with two crossed leverspivoted together, the forward ends of which are curved to form jaws, ofa staple-holder having a series of vertical angular recesses of asuitable depth adapted to receive staples of different sizes and acentral hole, a plunger-cap within the holder and shaped to conform tothe angular recesses therein, a plunger-stem one end of which is securedin one of the jaws, its other end being passed through the hole in theholder and secured to the plunger-cap, a coiled spring encircling thestem between the jaw and the holder, and a head-plate secured to theother jaw.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOSEPH P. HASTY.
